A referendum was held on Thursday 23 June 2016, to decide whether Britain should leave or remain in the European Union. A referendum is basically a vote in which everyone (or nearly everyone) of voting age can take part, normally giving a "Yes" or "No" answer to a question. Whichever side gets more than half of all votes cast is considered to have won. Why was a referendum held ? Prime Minister David Cameron promised to hold one if he won the 2015 General Election, in response to growing calls from his own Conservative MPs and the UK Independence Party (UKIP), who argued that Britain had not had a say since 1975, when it voted to stay in the EU in a referendum. The EU has changed a lot since then, gaining more control over our daily lives, they argued. Mr Cameron said: "It is time for the British people to have their say. It is time to settle this European question in British politics." What is the European Union ? The European Union - often known ...

Y esterday, 100 years later, scientists from Caltech, MIT and LIGO (Laser Interferometric Gravitational wave Observatory), announced in Washington that gravitational waves exist, predicted by Einstein in 1916, a century ago. It’s one of the most significant discoveries of the decade. Scientists who believe the discovery opens new vistas into the ‘dark’ side of the Universe. Scientists said they detected gravitational waves coming from two Black Holes – infinitely dense objects whose existence was foreseen by Einstein – that orbited one another, spiraled inward and smashed together. They said that the waves which detected in LIGO were the product of a collision between two Black Holes 30 times as massive as sun and located 1.3 billion Light Years from Earth. What are Gravitational Waves ? These are waves produced by disturbances in the fabric of space and time due to movement of a massive object like a Black Hole. They would appear like ripples in a pond. What is LIGO ? The La...
